Detailed description of the invention
Fig. 1 shows an embodiment of the printing sample according to the present invention obtained by curable compositions.
The embodiment that Fig. 2, Fig. 3 and Fig. 4 show the printing sample obtained by comparable curable compositions.
Specific embodiment
Curable compositions as described herein provide many advantageous features.
Curable compositions have specific coloring, and are very suitable for printing by increasing material manufacturing method such as SLA and add With processing.
It has also been discovered that curable compositions can be pocessed in increasing material manufacturing method, what which used Wavelength be in the range of 365nm to 405nm, this with for carrying out the manufacturing method (for example, whether it is digital light processing side Method (" DLP ") or cleaning piece method, that is, use scraper method) device it is unrelated.
Therefore, curable compositions as described herein can be solid using light substantially in any kind of increasing material manufacturing equipment Change is pocessed.
Due in curable compositions be not present inorganic colored pigments and/or inorganic filler, curable compositions and It is completely inflammable by its three-dimensional article produced.That is, pouring later may be negatively affected by not leaving after burning-up process Any residue of casting method (so-called " lost wax method " or " casting method ").
In addition, the curable compositions are convenient for creation precision architecture, i.e., since it includes the particular compositions of different dyes Make be small structure (such as in each dimension have lower than 10mm size.
The particular composition of different dyes allows to control light (especially UV light) and penetrates into curable and cured combination In object.By doing so, the cured risk of transition solidification or unwanted areas of curable compositions can be reduced.
In particular, it has been found that (methyl) acrylate based resin composition of the UV light curable of dark purple chromatic colorant is available In the accurate three-dimensional printed article of production.In solid state, printed matter seems with black surface.
If structure that is small and being decorated with metallized thread should be produced, this is especially useful.For example, for lingual bracket Increasing material manufacturing, curable compositions must satisfy particular/special requirement.
Due to being important in high precision, in this process, it is usually vital that product is visually inspected after printing.
One important method and step is to be manually removed or separate supporting element geometry from desired three-dimensional article.
Because orthodontic bracket usually has metallic yarn structure, the common 3D printing resin for hot investment casting is for small Path length (for example, if printing thin thin portion) seems substantially transparent.
Therefore, in many cases, practitioner be difficult to differentiate between whether correctly remove supporting element geometry or whether There are other artifacts.
Curable compositions as described herein solve the problems, such as this.Three-dimensional article obtained is dark color, and is being printed Black is even also substantially appeared as in thin layer later.
This is conducive to visually inspect three-dimensional article and removes support construction and unexpected artifact.
In addition, not only can easily visual detection to remaining printing artifact or support construction element, Er Qieke Easily for example forming, milling, mill or polishing by way of from three-dimensional article remove.It has been observed that raw by removing method The dust of production is brighter than the lower surface of three-dimensional article.Therefore, practitioner can easily determine to three-dimensional object surfaces which It is partially completed removing method.It has been found that this effect can be enhanced if reducing the granularity of dust.In the shape of three-dimensional article In the case where should being suitable for other reasons, this is also advantageous.
It has moreover been found that curable compositions as described herein for practitioner provide how in increasing material manufacturing machine (specific SLA printing machine) creation platform on to the more freedom for thering is three-dimensional article to be produced to be orientated.
